Speedrunner BubblesDelFuego completed a new world record Fallout 3 run in a ridiculous 23 minutes and 55 seconds, beating out his old record of 24 minutes and 20 seconds. I spent more time than that on my first playthrough repeating "Tunnel Snakes rule!" like a broken record, so that's impressive.

Bubbles used a number of common Fallout 3 strategies such as "load clipping", in which quick saving and loading can teleport you through certain obstacles, and using the same technique, skip dialogue segments. Bubbles also used a trick in which timing jumps uphill will keep the player's speed up instead of slowing it down as walking up the incline normally would do.
